MACHINE FOR USE IN MAKING BOXES.

Application filed April 15, 1921. Serial No. 461,536.

To all whom it may concern:

Be it known that I, CHARLES H. BOM- BARBIE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented an I mprovement in Machines for Use in Making Boxes, of which the following is a specification.

The invention relates to machines for use in making boxes, box blanks or parts thereof, and, among other objects, is intended to provide a machine of the class described having improved means for positioning the work.

One illustrative form of machine embody.- ing the invention is shown in the accom panying drawings, in which:

Fig. 1 is a side elevation of one type of wire bound box blank machine embodying the invention; 7

Fig. 2 is an enlarged cross section of one of the work-forwarding chains and its support showing the work-positioning means, said section being taken on the line A-A of Fig. 1;

Fig. 3 is an enlarged side elevation of one of the work-forwarding chains and its support seen from BB in Fig. 2.

The illustrative machine is of the type disclosed in the Reissue Letters Patent to O. G.'Thompson, No. 15,045, issued February 15, 1921, and consists generally of a gang of staplers 1 adapted to form staples from wire fed thereto and drive the staples overbinding wire into box parts progressively subjected to the action thereof. The box parts are assembled on endless conveyer chains 2 travelling in channel guides 3 on the supports 4 and are trained over sprocket wheels 5 and 6 respectively at either end of the machine. The work-forwarding chains 2 are advanced intermittently by a ratchet and pawl mechanism 7.

'In the manufacture of wire bound boxes, the materials are assembled on the workforwarding chains 2 and are spaced apart the desired distance by means of spacer blocks 8 which may be adjustably secured to a flange 9 of the work-forwarding chains. Thus in the manufacture of a four sided box, five spacer blocks 8 are used for each box assembly, one at either end of the box assembly and the other three between sections thereof. The endless work forwarding chains are usually of a length to accommodate from six to eight box assemblies de pending upon the size of the box desired although said chains may be lengthened .or shortened to accommodate a greater or lesser number of box assemblies. It is desirable that the blocks 8 on either work-for warding chain 2 be in exact alignment one with'the other to properly position the materials for each section of a box assembly and itis also desirablethat each group of spacer blocks 8 be positioned alike in order to produceboxes of uniform size and spacing. Applicant hastherefore provided positioning means for aligning the spacer blocks on the two parallel work-forwarding chains and which enables the operator to effect a like positioning and spacing of materialsfor a succession of box assemblies.

' Referring to Figs. 2 and 3,- the' positioning means comp-rises a series of positioning members 10 at either side of the machine, adjustably clamped to a shaft 11 by means of screws 12, said shaft 11 being adapted to revolve in brackets 13 secured to the support at by screws 14. Shafts .11 are provided at both sides of the machine and extend from a short distance in front of the staplers 1 parallel with the supports 4 to the front end of the machine. The brackets 13 nearest the staplers and the brackets 13 at the forward end of the machine are preferably fixed while the intermediate brackets are slidable within certain limits to ac-- commodate the positioning members 10. The positioning members 10 which lie nearest the staplers at eitherside of the machine are also preferably in fixed alignment one with the other so that the first spacer blocks of engagement with the work-forwarding chains and said chains are then advanced until the last spacer block. 8 has passed the first positioning member 10. The patterns ofpositioning members 10 are then swung back into position against the work-forwarding chains 2 and a spacer block 8 is secured to the work-forwarding chains adjacent each positioning member 10 thus positioning the second. group of spacer blocks to correspond with the first. This operation is repeated imtil all of the groups of spacer blocks have been properly'positioned on the Work-forwarding chains. The positioning members 10 are then wung outward and downward where'they remain until a new set-up oftheichain is required for a different sized box.

1 Thus it'will be noted that a pattern mechanismhas}. been. provided :for positioning aw'spacer blocker a group of spacer blocks onivione work-forwarding chain in exact alignment K-Wlth' another spacer block or igrouprofv spacer blocks on a parallel chain, andawhich is adapted to effect the same positioning ofia succ ession of blocks or" groups 7 ofblocks.

up the machine each time a different sized box isto be made because the pattern of positioning: members WilliPOSllZlOIl a succession of'groups of spacer blocks accordingto the pattern-thus eliminating the independ'ent'set 'up 'of each group of spacer blocks. 7 Another advantage is that with applicants device unskilled labor may be employed to set up the machine after the patternuof positioning members isonce set up.

-Heretofore in setting up the spacer blocks on :the-work-forwarding chains the operator first had to adjust the first blocks ofthefirst group of blocks as-nearly in aligninentas he was able to place them andthen measure oil the required distances of each succeeding block of each succeedinggroup of-blocks all around the work-forwarding chains. This was a long and laborious operation and very often resulted'inz-improper alignment: of the blocks. Y In applicants machine the positioning members for the first spacer block are fixed in exact alignment-soythat it is impossible for the first blocks to be out ofline. lvith the first positioning members in exact alignment it is simple matter to locate the succeeding members for a box assembly the proper distancesitherefrom. With the pattern of positioning members thusproperly setfor one box assembly lall'the groups of spacer blocks onthe Work-forwarding chains may be quickly and accurately set in accordance with the pattern.

It will be understood that the illustrative box blank machine is only one of several typesrand that applicants invention is susceptible of embodiment in machines of other types and in various combinations and subcombinationsl Having describedclaimed is: H r

1. A machine for use in making boxes comprisingfln combination, work-forwarding means including box part positioning members; binding-'Wire-applying mecha nism; and means to control the location of said positioning members to position a group of box parts in predetermined spaced relationship on said work-forwarding means, said controlling members being adapted 'to control a succession of groups of positioning members to position a succession of groups of box parts in like spaced relationship.

A machine for use in making boxes comprising, in combination, work-forwarding means --compr1sing parallel conveyors having adjustable members for positioning box parts thereon; binding-wire-applying mechanism; and means to align'a group of spaced positioning members on one conveyer opposite a similarly spaced group of positioning members on the other conveyer, said means being adapted to similarly ali-gn a succession of such groups. 7
